Abstract: In this article, a novel approach on miniaturization of a simple rectangular patch has been discussed. Microstrip feed line has been used to excite the structure at 2.45 GHz. By introducing circular slots in the patch the design has been optimized. The impact on reflection coefficient and overall size due to slots of different radius is studied thoroughly. To achieve better impedance matching and desirable antenna gain, a 3x3 array of Split Ring Resonator (SRR) is introduced at the ground plane. CST MICROWAVE STUDIO is used for the necessary simulation.

TL;DR: In this paper , the authors applied the metamaterial technique of miniaturization on the ground of 3.3 GHz conventional patch antenna in order to conceive a new antenna that resonates at 2.45 GHz suitable for WLAN applications.
Abstract: In this paper, the metamaterial technique of miniaturization was applied on the ground of 3.3 GHz conventional patch antenna in order to conceive a new antenna that resonate at 2.45 GHz suitable for WLAN applications. Two symmetric metamaterial (MTM) square unit cells based on complementary split ring resonator (CSRR) were etched on the ground plane of the antenna. The conception was done with FR-4 dielectric as a substrate, its permittivity is 4.4 and its loss tangent is 0.0025, and cooper annulled as metal for radiating element and the ground. The simulation was done by CST solver. The new conceived 2.45 GHz metamaterial antenna is 45.7% smaller than 2.45 GHz conventional patch antenna and has gain of 2.33 dB and band width of 103 MHz.

Abstract: A survey of microstrip antenna elements is presented, with emphasis on theoretical and practical design techniques. Available substrate materials are reviewed along with the relation between dielectric constant tolerance and resonant frequency of microstrip patches. Several theoretical analysis techniques are summarized, including transmission-line and modal-expansion (cavity) techniques as well as numerical methods such as the method of moments and finite-element techniques. Practical procedures are given for both standard rectangular and circular patches, as well as variations on those designs including circularly polarized microstrip patches. The quality, bandwidth, and efficiency factors of typical patch designs are discussed. Microstrip dipole and conformal antennas are summarized. Finally, critical needs for further research and development for this antenna are identified.

Abstract: Electrically small microstrip patches incorporating shorting posts are thoroughly investigated. These antennas are suitable for mobile communications handsets where limited antenna size is a premium. Techniques to enhance the bandwidth of these antennas are presented and performance trends are established. From these trends, valuable insight to the optimum design, namely broad bandwidth, small size, and ease of manufacturing, is given.

TL;DR: The Fabry-Perot like resonance model has been introduced to analyze the enhancement mechanism of asymmetric transmission in the multi-layered structure and results reveal that the structure realizes a high magnitude of 0.94, three bands and broadband asymmetric Transmission for linearly polarized wave.
Abstract: In this paper, a multi-layered metallic structure is proposed, which consists of split-ring resonators on both sides of two dielectric substrates. Numerical results reveal that the structure realizes a high magnitude of 0.94, three bands and broadband (more than 8 GHz) asymmetric transmission for linearly polarized wave. These properties are not observed in previous works. In order to better know these transmission properties, the Fabry-Perot like resonance model has been introduced to analyze the enhancement mechanism of asymmetric transmission in the multi-layered structure. The physical mechanism of linearly polarized wave conversion and asymmetric transmission based on electric fields and currents distribution is also analyzed in detail, respectively.
